Why is it a Noxious Weed?

It spreads very fast and outcompetes native flora. Can form dense monocultures in forest understories and open woodlands.

False Brome is spreading quick through Oregon, and has already popped up in a few Washington counties, including Cowlitz Co. to our south. If you spot any False Brome please let us know.
